activity in the total cell fraction [i.e. cells collected from combined PVC/MR
(pavement cell/mitochondria-rich) fraction, the 1.031.09 g
ml1 Percoll interface]. Freshwater control fish compared
with both 10
and 30
seawater-adapted fish. Significant
differences are indicated by different letters. Values represent means
± S.E.M. (N=46
fish).
